gnulib: let it use its own PO domain

See
https://www.gnu.org/software/gnulib/manual/html_node/Localization.html.

* bootstrap.conf: Create gnulib-po.
* Makefile.am, configure.ac: Use it.
* po/POTFILES.in: Remove files now in gnulib.
* src/main.c: Open the bison-gnulib domain.

 ** use gettext-h in gnulib instead of gettext

-For some reason, according to syntax-check, we have to keep getopt.c in
-POTIFILES.in, but not bitset/stats.c, although both come from gnulib.  But
-bitset/stats.c is a symlink, not getopt.c.  This is fishy and should be
-fixed.

-Meanwhile, bitset/stats.c is removed from the set of translations, which is
-not too much of a problem as users are not expected to see this.
